The flowchart shows social pressures toward extreme thinness leads to negative body image. Overvaluation of appearance, perfectionism, low self-esteem, et cetera leads to anxiety and depression, and excessive dieting. Genetic predisposition leads to both negative body image and anxiety and depression, and excessive dieting. Negative body image leads to excessive dieting. Anxiety and depression lead to excessive dieting and impulsive binge eating. Excessive dieting leads to impulsive binge eating, which further leads to compensatory behaviors (purging, excessive exercise), and finally leads to Bulimia nervosa. Impulsive binge eating leads back to anxiety and depression and binge-eating disorder. After excessive dieting, if successful in losing weight, reinforced by society and sense of control, it leads back to excessive dieting and further to Anorexia nervosa.
